    not a problem simon2004 oil gets in to inter cooler pipes from crankcase vent or turbo seal mines from crankcase vent.so im fitting oil catch can apparently its better for the engine not to burn oil.

    it all depends on which way you want to do it,

    for example on my old turbo almera (petrol) (engine transplant) i fitted one from the cam cover to a catch tank then the pipe from the catch tank, down the back of the engine bay, reason why, with just a little filter on there you could smell the fumes

    i'd personaly take the pipe that goes from the crank case, put that into a catch tank, then the pipe out of it back into the inlet, or, from the crank, into a catch tank, then pipe out to air (with little filter) and block of the pipe on the intake side

    Thanks scott b

    Reason i asked was if CCV needed the vacume from intake pipe

    I think ill run pipe down bulkhead under car from catch can did you say you put small filter end of pipe because i was thinking keep it open in case gets blocked.
    thanks bradster
